Be it known that I, CHARLES S. SHARP, of

Auburn, in the county of Oayugaand State'of New-York, have invented acertain new and useful Mowing-Machine, of which the following is aspeciiication. f

My invention has for its lobject the production of particularly simple,economical, and efficient connections between the lnger-bar andcoupling-frame of a mower; and it consists in the combination,construction, and arrangement of the component parts of the contiguousportions of said finger-bar and frame and the connections between thesame, as hereinafter fully described, and pointed out in the claim.

In describing this invention reference is had to the accompanyingdrawings, forming part of this specification, in which like lettersindicate corresponding parts in all the views.

Figure 1 is a top plan of a mowing-machine embodying my invention, aportion of the pole being broken away. Fig. 2 is an enlarged top plan ofcontiguous portions of the finger-bar and the coupling-frame opera-.tively connected together. Fig. 3 is avertical sectional view taken online 3 3, Fig. 1. Fig. 4 is a horizontal sectional view of the frontconnection between the finger-bar and the coupling-frame. Fig. 5 is arear elevation of the detached inner shoe for the fingerbar and theadjusting member journaled in said shoe. Fig. 6 is a horizontalsectional view taken on line 6 6, Fig. 5. Fig. 7 is an enlarged planview, partly'in section, of a portion of the parts seen in Fig. 2. i

A and B represent, respectively, the {ingerbar and the coupling-frame ofmy mowingmachine, both of which parts may be of any suitable form, size,and construction. Said tinger-bar A and coupling-frame B are provided,respectively, with aninner shoe a and ayoke b, which, so far as thisinvention is concerned, form, essentially, parts of theiinger-bar andthe coupling-frame. The yoke is provided with a socket b', extendingfrom the rear forwardly and having lsubstantially vertical side walls b2bias best shown in Figs. 2 and 3, and a seating. 61,979. @modela Ldiagonalpush-barts, forming part ofthe A'couplingframe Bhasafforward-extension 64,

projecting.intothe socket- The extension of Athepush-baris providedwithan eye, through which theend ofthe frame-bar b5 extends, The yoke .b.is journaled upon the bar 65,.-and the extension b4 of the -bar 3cooperates with the vertical walls b2 on its opposite sides and limitsthe endwise movement of the yoke on the frame-bar b5. p

The finger-bar A, or, more strictly speaking, its inner shoe a, isprovided with separated relatively fixed attaching parts or ears a' a2,which rise upwardly from the contiguous portions Yof said finger-har,are arranged one in advance of the other, and are connectedindependently to the coupling-frame B, and preferably to attaching partsor ears t 67, depending from the yoke t, and also arranged one inadvance-of the other.

v The'parts or ears a b are connected by a substantially horizontalpivot e, Fig. A, which Vhas a limited play in a slot in the ear b, andthe contiguous surfaces of said parts or ears a be are formedconcavo-conveX, so that tlie surface of the part or ear a' adjacent tothe part or ear b is free to move relatively to said part or ear b asthe outer end of the fingerbar is forced forwardly or backwardly.

The parts or ears co2 67 are connected by an adjusting member o" and asubstantially horizontal pivot o?, Figs. 6 and 7, the adjusting member cbeing journaled in the part or ear a2 and provided with aneccentrically-arranged opening and the pivot 02 being passed through thepart or ear 67 and through the eccentrically-arranged opening in theadjusting member 0 and alined with the pivot c transversely to thelength of the finger-bar A. Said adjusting member c may be held inposition by any suitable means, as a bolt 03, engaged with' partlyrotated in the attaching part or ear a2, thus moving said part or earlaterally relatively to the other part or ear a without varying thealinement of the pivots c c2. During the adjustment of the linger-bar bythe member c" the part or ear a is free to move relatively to the partor ear b to a limited extent for permitting the desired movement of thepart or ear a2. After the desired adjustment of the outer end of thefinger-bar the bolt 03 is tightened, whereupon said finger-bar is heldin its adjusted position. When adjusting the linger-bar, it is usuallyunnecessary to adjust the bolt c; but it will be understood that saidbolt may be adjusted, if desired.

The construction and operation of my mowing-machine will now be readilyunderstood upon reference to the foregoing description andv theaccompanying drawings, and it will be particularly noted that more orless change may be made in the component parts thereof Without departingfrom the spirit of my invention.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is-

In a mowing-machine, the combination of a coupling-frame bar, a yokemounted on the coupling-frame bar and provided with a socket extendingforwardly from a rear face thereof, and a diagonal push-bar formed witha forward extension projecting into the socket and connected to thecoupling-frame bar, said extension eoperating with the side walls of thesocket to limit the endwise movement of the yoke on the coupling-framebar, substantially as and for the purpose described.

In testimony whereof I have hereunto signed my name, in the presence oftwo attesting witnesses, at Auburn, in the county or' Cayuga, in theState of New York, this 10th day of May, 1901.

CHARLES S. SHARP.
